A key issue in developmental biology at that time was the problem of how cells underwent differentiation, with most workers concentrating on explanations in terms of changes in enzyme and gene regulation.
Like Honeycrisp, SweeTango has much larger cells than other apples, and when you bite into it, the cells shatter rather than cleaving along the cell walls, as is the case with most popular apples. The bursting of the cells fills your mouth with juice. Chunks of SweeTango snap off in your mouth with a loud cracking sound.
In cross-country skiing, athletes propel themselves over distances of ten and twenty miles - a physical challenge that places intense demands on the ability of their red blood cells to deliver oxygen to their muscles.
Broccoli is incredible. It can prevent DNA damage and metastatic cancer spread; activate defences against pathogens and pollutants; help to prevent lymphoma; boost the enzymes that detox your liver; target breast cancer stem cells; and reduce the risk of prostate cancer progression.
So why in the world would anyone support the unethical, failed use of embryonic stem cells instead of the ethical, successful use of adult stem cells? Because they do not know the difference.
Lithium makes a fine battery because it's a scarily reactive metal. Pure lithium ignites on contact if it touches water - a flake of it would sizzle and fry on the water-rich cells of your skin.
It is unlikely that changes in telomeres are influencing the lifespan of the worm. That is because telomeres only shorten when cells divide. Most of the cells of the worm stop dividing when the worm becomes an adult.
I've always drawn, for example, and I did consider when I was younger, it was either do I become an actor or do I become an animator cartoonist at that point. Do I work at Disneyworld or something and do animated cells or something?
We have found that morals are not, like bacon, to be cured by hanging; nor, like wine, to be improved by sea voyages; nor, like honey, to be preserved in cells.
What I have is P.H. positive chronic myeloid leukemia, which is an aberration in your white blood cells.
Throughout our lifetimes, we are constantly regenerating new brain cells in the hippocampus, a process called neurogenesis. New stem cells are constantly being born in the hippocampus that ultimately differentiate into fully functional neurons.
Producing fuel cells and solar panels requires high tech facilities and produces high paying jobs. The industry is booming in Arizona. The state already has about 100 firms in the solar industry and has grown 20% since 2003.
My fat cells have a memory like Einstein! I'm proof that surgery is not a magic potion. There are many ways to sabotage it.
Most organisms have loads of junk DNA - less pejoratively, noncoding DNA - cluttering their cells.
Stem cells are being used for anti-aging, and the University of Miami is doing a study about that to prove that it is true. They are looking at me, and my markers have shown exactly that I have been actually reversing my aging and getting younger. I am taking perhaps more stem-cell treatment than anybody else in the world.
The best standardisation committee in the world is nature herself, but in nature standardisation occurs mainly in connection with the smallest possible units: cells. The result is millions of flexible combinations in which one never encounters the stereotyped.
You could double the number of synaptic connections in a very simple neurocircuit as a result of experience and learning. The reason for that was that long-term memory alters the expression of genes in nerve cells, which is the cause of the growth of new synaptic connections.
In my experience of living, for a time, in the underbelly of society, I spent a lot of time in various holding cells.
Almost always, when we have fights in movies, they're done in these strange rooms where nothing gets broken. It's almost like they're in padded cells.
Water is commonly regarded as the 'solvent of life,' since our bodies are 70% water. All other vertebrates, invertebrates, microbes, and plants are also primarily water. The organization of water within biological compartments is fundamental to life, and the aquaporins serve as the plumbing systems for cells.
We know that our cells are speaking to each other.
There are nations, where people live in captivity, fear and silence. I believe, one day from prison camps and torture cells and from exile the leaders of freedom will emerge. The world should stand with those oppressed people until the day of their freedom finally arrives.
The number of cells in our bodies is defined by an equilibrium of opposing forces: mitosis adds cells, while programmed cell death removes them. Just as too much cell division can lead to a pathological increase in cell number, so can too little cell death.
Your brain is built of cells called neurons and glia - hundreds of billions of them. Each one of these cells is as complicated as a city.
To say that my anxiety is reducible to the ions in my amygdala is as limiting as saying that my personality or my soul is reducible to the molecules that make up my brain cells or to the genes that underwrote them.
It's incorrect to think of bacteria as these asocial, single cells. They are individual cells, but they act in communities, exactly the way people do.
One of the first papers I wrote at the University of Wisconsin, in 1977, was on stem cells. I realized that if I changed the environment that these cells were in, I could turn the cells into bone, and if I changed the environment a bit more, they would form fat cells.
Just when your ovaries should be brimming with youthful follicles, cancerous cells overtook mine, threatening to end my fertility and potentially my life.
I wondered whether the nuclear transfer techniques could be used to introduce purified macro-molecules into an egg, and hence into embryonic cells.
A human body is a conversation going on, both within the cells and between the cells, and they're telling each other to grow and to die; when you're sick, something's gone wrong with that conversation.
At the end of the 1970s, I was a young researcher at the Weizmann Institute with an ambitious plan to shed light on one of the major outstanding questions concerning living cells: the process of protein biosynthesis.
Everything one reads is nourishment of some sort - good food or junk food - and one assumes it all goes in and has its way with your brain cells.
Those revolutionaries who have, by chance, escaped the gallows should live and show to the world that they cannot only embrace gallows for the ideal but also bear the worst type of tortures in the dark, dingy prison cells.
If you're black and have leukemia, the chances of finding a donor are drastically reduced. I added my name to the register, and lo and behold, six months later, I was asked to donate. I had a week of 'conditioning' where I had to take these pills and injections to create new stem cells in my body.
The actual organization of behavior goes on the level of the individual nerve cells and their connections, and we have a hundred billion nerve cells, probably a hundred trillion connections. It's just mind-boggling to think of all the different ways in which they're arranged in a baby's head.
For a very long time, we've been extraordinarily interested in the interaction between low temperature and low oxygen. We see that they're connected because we know people who are extremely cold are not getting oxygen to their cells. And yet, they're sometimes alive.
